* Mark Twain: Known for his sharp wit and social commentary, Twain satirized American imperialism, particularly in works like "The Man That Corrupted Hadleyburg" (which subtly critiques the moral hypocrisy fueling expansionism) and his writings on the Philippine-American War, though not always in overtly satirical forms. His essays and speeches directly criticized the war's injustices.
* Joseph Conrad: While not purely satirical, Conrad's *Heart of Darkness* is a powerful critique of colonialism using dark irony and unsettling imagery. It exposes the brutality and psychological toll of imperialism, achieving a satirical effect through its unsettling portrayal of ostensibly "civilizing" actions.
* Rudyard Kipling (ironically): While initially a proponent of imperialism, Kipling's later works, such as some of his poems reflecting on the realities of empire, arguably contain elements of satire, revealing the contradictions and moral compromises of the imperial project. However, he's a more complex case, as his intent is often debated.
It's important to note that many other writers used satire to critique colonialism and imperialism in different parts of the world and throughout history. The specific writers and their works depend heavily on the specific aspect of imperialism being satirized and the historical context.
